I would say I definitely "hated" it as a snot nosed teen punk, but I've softened my stance on some Prog bands as I've gotten older. My cousin convinced me to check out Yes a few years ago. Jon Anderson was no longer in the group...but they played 3 albums from start to finish. I didn't think I'd like it, but I kind of did.

Depends. There's some truly awful stuff out there under the prog rock monicker, but that's the ELP shit I can't stand. King Crimson and Hawkwind alone are proof that the genre can rule, tho.

I was going to mention ELP as one of the prog bands I really hated. I think it can be very inventive and interesting, but then it can be very indulgent and boring. I like some of the stuff Genesis did when Peter Gabriel fronted the band - very imaginative and weird - but not boring.

It depends greatly on the artist and the definition. eumaas mentioned Can, which I love, and others have cited ELP, which I can't stand. I'm generally favourable to "art rock," which is a kissing cousin of prog, so, yeah, depends.

I won't say any single style or genre is all bad anymore. I favor some over others and tend not to favor a lot of the prog Ive heard. King Crimson has been mentioned and I do like some of their stuff. My brother went thru a pretty serious prog rock phase and as he was older and bigger and we shared a room I've heard my share of it. I do find a lot of it to be fairly boring, though I can appreciate the musicianship of some them.
